Home / Blog / Intellectual Property (IP) / Untangling Patent Thickets: The Hidden Barriers Stifling Innovation

1. Introduction 

In the rapidly evolving landscape of technology and innovation, patent thickets have become a significant and often contentious issue. 

A patent thicket refers to a dense web of overlapping patents held by multiple entities, creating a complex environment for navigating intellectual property rights.

These thickets can have profound implications on innovation, particularly in industries such as pharmaceuticals, biotechnology, and digital communications. 

Patent thickets arise when numerous patents cover similar or related technologies, making it challenging for new entrants to develop or commercialize new products without infringing on existing patents

This scenario can lead to increased costs and legal risks, potentially stifling innovation and slowing the pace of research and development (R&D. 

The formation of patent thickets is often driven by strategic patent filings aimed at protecting market positions and deterring competition.

For instance, in the pharmaceutical industry, companies may file multiple patents related to a single drug to extend their market exclusivity and delay the entry of generic competitors.  

A notable example is AbbVie’s blockbuster drug Humira, which has been surrounded by a dense thicket of over 250 patents, protecting various aspects of the drug and its delivery mechanisms. 

While patent thickets can create barriers to entry and increase litigation costs, they can also promote cross-licensing and collaboration among companies.

Patent pools, where multiple patent holders agree to cross-license their patents, can help mitigate the negative effects of thickets by reducing transaction costs and facilitating access to essential technologies.

4. Strategies for Navigating Patent Thickets

Given the complex and often challenging nature of patent thickets, various strategies can be employed to navigate and mitigate their impact. 

These strategies range from collaborative approaches like patent pooling to policy reforms aimed at reducing the creation and impact of patent thickets.

4.1. Patent Pooling and Cross-Licensing

Patent pooling is a strategy where multiple patent holders agree to license their patents to each other or to third parties. 

This approach can reduce litigation and lower transaction costs, making it easier for companies to access necessary technologies. 

Cross-licensing agreements, where companies grant each other licenses to use their patented technologies, can also alleviate the restrictive effects of patent thickets and promote innovation.

4.1.1. Case Study: MPEG LA

The MPEG LA patent pool, which manages patents essential to the MPEG-2 video compression standard, is a successful example of patent pooling. 

By aggregating patents from multiple holders and offering them under a single license, MPEG LA has facilitated the widespread adoption of this technology while minimizing litigation and licensing costs.

4.2. Open Innovation and Collaborative Platforms
